Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478164, here are decompositions:
- 7 + 478157 = 478164
- 53 + 478111 = 478164
- 97 + 478067 = 478164
- 101 + 478063 = 478164
- 163 + 478001 = 478164
- 173 + 477991 = 478164
- 191 + 477973 = 478164
- 223 + 477941 = 478164
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 478,164 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 478164 first appears in π at position 5,751 of the decimal expansion (the 5,751ordinal-suffix:st digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
